What does Psalm 24:10 mean?

This closing verse of Psalm 24 describes the glorious King as "the LORD of hosts." This divine title occurs well over two hundred times in the Old Testament. Its first occurrence is in 1 Samuel 1:3. Isaiah and Jeremiah combined use this phrase well over one hundred times.

The name "LORD of hosts" identifies the Lord as eternal and ruler over all the angels and stars. The title reflects the truth that, although Israel's earthly king was David, her real king was Yahweh. Prophetically, the glorious king who will enter Jerusalem is the Lord Jesus. He is the Lord of heaven and earth by virtue of creation and redemption. Colossians 1:15–17 describes Jesus as having created everything in heaven and on earth, not only visible objects but invisible. The invisible would include the angelic host. He also holds everything together. Someday the Lord of hosts will return to earth with mighty angels to execute judgment on unbelievers and to reign from the throne of David (Isaiah 9:6–7).
